Rasp Worries
I'm currently installing LT's and an ORY. I know rasp is going to be inevitable. For now, I'll be running stock mufflers on the SS. So what I was thinking to reduce rasp is to install a bullet muffler on the stock I-pipe or possibly installing a high flow cat in that same spot. My question is has anyone put a cat that far back in the system? I'm not concerned with monitoring it with O2's or anything, just would want to reduce rasp and exhaust smell. Any suggestions or feedback to this idea....????

Don't try to put a cat that far back. There is no way to put one in the back of the exhaust where if it lights off you won't burn a hole in your carpet. If you are really concerned with the rasp look at this post by Patrick G in the internal engine section. The "recipe" to 500 rwhp with heads and cam.

If you've got the basic SS exhaust (not the dual dual) it will be raspy, I had the same setup, didnt sound very good. I've never heard one with a bullit in the I-pipe but I would think it would help.

Pacesetters w/tsp none catted y-pipe.Hooker catback.
I had that terrible rasp sound mainly from 2200-3500 rpm.Full throttle wasn't
bad but noticeable.Put a Flowmaster 3-3.5 merge collector on,best money spent.IMO. Don't know if it helped perfomance but it does make a differance
in the sound.
